Under the three backgrounds of policy, environment and energy, the development of new energy electric vehicles has become a global consensus. New energy vehicle cables are mainly divided into two categories: on-board cables and non-vehicle cables, that is, in-vehicle cables and charging pile cables. The in-vehicle cables are further divided into high-voltage cables and low-voltage cables, and high-voltage cables are used in new energy vehicles. Application comparison Many, so focus on some differences between high-voltage cables and charging cables.

1. Different international standards

The international standard for high-voltage cables is formulated by the ISO organization; the international standard for charging cables is formulated by the IEC organization.

2. Different color requirements

Internationally, it is stipulated that the color of automobile high-voltage cables is orange, which plays the role of warning of high voltage; there is no requirement for the color of charging cables.

3. Different laying methods

Cable laying generally refers to the routing method of cables from the distribution box to the electrical equipment or another distribution box. High-voltage cables belong to fixed laying, but the static bending radius of individual points is small; charging cables belong to mobile laying, and the dynamic bending radius is small.

4. The number of cable cores is different

In order to facilitate the laying of automobile high-voltage cables, they are usually single-core; the charging cable is usually a multi-core integrated wiring harness, which includes high-voltage main lines, ground lines, low-voltage signal lines, and even communication double-effect lines (CAN). )and many more.

5. Different heat resistance

The higher the heat resistance of the high-voltage cable, the better, the better the heat resistance, and the greater the current carrying capacity, so the minimum requirement is 125 degrees, and the heat resistance of silicone rubber and fluororubber can even reach 180 degrees and 200 degrees; and the charging cable is usually exposed to Outside, it should not be too hot, preferably not more than 70 degrees, otherwise it is easy to burn.

6. Different EMI requirements

Electromagnetic compatibility (EMC) is a comprehensive evaluation of the magnitude of electromagnetic field interference (EMI) and anti-interference capability (EMS) of electronic products, and is one of the more important indicators of product quality.

High-voltage cables have high requirements for EMI. In order not to affect the in-vehicle communication control function, they must meet the EMC standards of the entire vehicle; while the vehicle is in a stationary state when the car is charging, the charging cable does not need to meet the EMC standards of the car, but it needs to meet the relevant EMC standards. EMC standards for environments such as gas stations and residential areas.

7. Different protection measures

The high-voltage cable is used in a complex environment, and necessary protection measures need to be taken around it; while the charging cable has no protection measures, but needs to be able to withstand various shocks and UV exposure.

8. Different physical performance requirements

High-voltage cables have higher requirements for wear resistance; charging cables have higher requirements for resistance to rolling.

9. Different chemical resistance

Automotive high-voltage cables need to withstand various liquids in contact with the car; charging cables must withstand various liquids in the living environment outside the car.

10. Different size requirements

The high-voltage cable has a small wiring space and has strict requirements on the size. Generally, the smaller the size, the better; the charging cable basically has no size limit, and the wire diameter can be made very thick and large.
